How many sensors can I add to a Hub?
---------------------------------------------------
- It should be noted that there is no limit to the number of devices that can be added to the MOCREO account.
  
- For `ST3 <./st3-user-guide.html>`_ / `ST4 <./st4-user-guide.html>`_ sensors, a single Hub can establish a maximum of 10 binding relationships with Sensors.

- For `SS1 <./ss1-user-guide.html>`_  / `ST5 <./st5-user-guide.html>`_ / `ST6 <./st6-user-guide.html>`_ / `ST9 <./st9-user-guide.html>`_ / `ST10 <./st10-user-guide.html>`_ / `SW2 <./sw2-user-guide.html>`_ sensors, instead of being bound to the Hub, the Sensors are directly bound to the MOCREO account. Within the Bluetooth scanning range of a single Hub, up to 30 Sensors can be deployed. If the Hub has already established binding relationships with 10 ST3/ST4 Sensors, the maximum number of Sensors that can be deployed within the Hub's Bluetooth scanning range is 25.

- For `ST7 <./st7-user-guide.html>`_ / `ST8 <./st8-user-guide.html>`_ sensors, there is no need to bind them to the Hub; they are directly bound to the MOCREO account.
